Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Organization and Summary of Significant Accounting Policies | 1. Organization and Summary of Significant Accounting Policies Dynavax Technologies Corporation (“we,” “our,” “us,” “Dynavax” or the “Company”), is a commercial stage biopharmaceutical company developing and commercializing novel vaccines. We launched our first product, HEPLISAV-B® [Hepatitis B Vaccine (Recombinant), Adjuvanted], in February 2018, following United States Food and Drug Administration (“FDA”) approval for prevention of infection caused by all known subtypes of hepatitis B virus in adults age 18 years and older. We were incorporated in California in August 1996 under the name Double Helix Corporation, and we changed our name to Dynavax Technologies Corporation in September 1996. We reincorporated in Delaware in 2000. On May 23, 2019, we implemented a strategic organizational restructuring, principally to align our operations around our vaccine business and significantly curtail further investment in our immuno-oncology business. In connection with the restructuring, we reduced our workforce by approximately 80 positions, or approximately 36%, of U.S.-based personnel. We expect the restructuring to be substantially complete and the related costs incurred and paid by December 31, 2019. We are exploring strategic alternatives for our immuno-oncology business. Basis of Presentation Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X. In our opinion, these unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which we consider necessary to present fairly our financial position and the results of our operations and cash flows. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted. Interim-period results are not necessarily indicative of results of operations or cash flows to be expected for a full-year period or any other interim-period. The condensed consolidated balance sheet at December 31, 2018 has been derived from audited financial statements at that date, but excludes disclosures required by GAAP for complete financial statements. The unaudited condensed consolidated financial statements and these notes should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018, as filed with the Securities and Exchange Commission (the “SEC”). The unaudited condensed consolidated financial statements include the accounts of Dynavax and our wholly-owned subsidiary, Dynavax GmbH. All significant intercompany accounts and transactions among these entities have been eliminated from the condensed consolidated financial statements. We operate in one business segment: discovery, development and commercialization of novel vaccines. Liquidity and Financial Condition As of September 30, 2019, we had cash, cash equivalents and marketable securities of $174.9 million. The Company has incurred losses and negative cash flows from operations since its inception and expects to incur operating losses for the foreseeable future as we continue to invest in commercialization of HEPLISAV-B. If we cannot generate a sufficient amount of revenue from product sales, we will need to finance our operations through strategic alliance and licensing arrangements and/or future public or private debt and equity financings. Adequate financing may not be available to us on acceptable terms, or at all. As of June 30, 2019, there was substantial doubt about the Company’s ability to continue as a going concern since it did not have sufficient financial resources available to fund its operations beyond the first quarter of 2020. In August 2019, the Company completed an underwritten public offering of common stock, non-voting preferred stock and warrants to purchase common stock resulting in net proceeds of $65.6 million. We currently anticipate that our cash, cash equivalents and short-term marketable securities as of September 30, 2019, and anticipated revenues from HEPLISAV-B will be sufficient to fund our operations for at least the next 12 months from the date of this filing. Our ability to raise additional capital in the equity and debt markets, should we choose to do so, is dependent on a number of factors, including, but not limited to, the market demand for our common stock, which itself is subject to a number of development and business risks and uncertainties, our creditworthiness and the uncertainty that we would be able to raise such additional capital at a price or on terms that are favorable to us. Raising additional funds through the issuance of equity or debt securities could result in dilution to our existing stockholders, increased fixed payment obligations, or both. In addition, these securities may have rights senior to those of our common stock and could include covenants that would restrict our operations . Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make informed estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Management’s estimates are based on historical information available as of the date of the condensed consolidated financial statements and various other assumptions we believe are reasonable under the circumstances. Actual results could differ materially from these estimates. Summary of Significant Accounting Policies Revenue Recognition We recognize revenue when the customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements that we determine are within the scope of Accounting Standards Codification (“ASC”) 606, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determine those that are performance obligations, and assess whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Product Revenue, Net We sell our product to a limited number of wholesalers and specialty distributors in the U.S. (collectively, our “Customers”). Revenues from product sales are recognized when we have satisfied our performance obligation, which is the transfer of control of our product upon delivery to the Customer. The timing between the recognition of revenue for product sales and the receipt of payment is not significant. Because our standard credit terms are short-term and we expect to receive payment in less than one-year, there is no financing component on the related receivables. Taxes collected from Customers relating to product sales and remitted to governmental authorities are excluded from revenues. Overall, product revenue, net, reflects our best estimates of the amount of consideration to which we are entitled based on the terms of the contract. The amount of variable consideration is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. If our estimates differ significantly from actuals, we will record adjustments that would affect product revenue, net in the period of adjustment. Reserves for Variable Consideration Revenues from product sales are recorded at the net sales price, which includes estimates of variable consideration such as product returns, chargebacks, discounts, rebates and other fees that are offered within contracts between us and our Customers, healthcare providers, pharmacies and others relating to our product sales. We estimate variable consideration using either the most likely amount method or the expected value method, depending on the type of variable consideration and what method better predicts the amount of consideration we expect to receive. We take into consideration relevant factors such as industry data, current contractual terms, available information about Customers’ inventory, resale and chargeback data and forecasted customer buying and payment patterns, in estimating each variable consideration. The variable consideration is recorded at the time product sales is recognized, resulting in a reduction in product revenue and a reduction in accounts receivable (if the Customer offsets the amount against its accounts receivable) or as an accrued liability (if we pay the amount through our accounts payable process). Variable consideration requires significant estimates, judgment and information obtained from external sources. The amount of variable consideration is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. If our estimates differ significantly from actuals, we will record adjustments that would affect product revenue, net in the period of adjustment. If we were to change any of these judgments or estimates, it could cause a material increase or decrease in the amount of revenue that we report in a particular period. There have been no material adjustments to these estimates for the nine months ended September 30, 2019. Product Returns: Consistent with industry practice, we offer our Customers a limited right of return based on the product’s expiration date for product th at has been purchased from us. We estimate the amount of our product sales that may be returned by our Customers and record this estimate as a reduction of revenue in the period the related product reven ue is recognized. We consider several factors in the estimation of potential product returns including expiration dates of the product shipped, the limited product return rights, available information about Customers’ inventory , shelf life of the product and other relevant factors. Chargebacks: Our Customers subsequently resell our product to healthcare providers, pharmacies and others. In addition to distribution agreements with Customers, we enter into arrangements with qualified healthcare providers that provide for chargebacks and discounts with respect to the purchase of our product. Chargebacks represent the estimated obligations resulting from contractual commitments to sell product to qualified healthcare providers at prices lower than the list prices charged to Customers who directly purchase the product from us. Customers charge us for the difference between what they pay for the product and the ultimate selling price to the qualified healthcare providers. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and accounts receivable. Chargeback amounts are determined at the time of resale to the qualified healthcare providers by Customers, and we issue credits for such amounts generally within a few weeks of the Customer’s notification to us of the resale. Reserves for chargebacks consists of credits that we expect to issue for units that remain in the distribution channel inventories at each reporting period end that we expect will be sold to the qualified healthcare providers, and chargebacks for units that our Customers have sold to the qualified healthcare providers, but for which credits have not been issued. Trade Discounts and Allowances: We provide our Customers with discounts which include early payment incentives that are explicitly stated in our contracts, and are recorded as a reduction of revenue in the period the related product revenue is recognized. Distribution Fees: Distribution fees include fees paid to certain Customers for sales order management, data and distribution services. Distribution fees are recorded as a reduction of revenue in the period the related product revenue is recognized. Rebates: Under certain contracts, customers may obtain rebates for purchasing minimum volumes of our product. We estimate these rebates based upon the expected purchases and the contractual rebate rate and record this estimate as a reduction in revenue in the period the related revenue is recognized. Collaboration and Manufacturing Service Revenue We have entered into collaborative arrangements and arrangements to provide manufacturing services to other companies. Such arrangements may include promises to customers which, if capable of being distinct, are accounted for as separate performance obligations. For agreements with multiple performance obligations, we allocate estimated revenue to each performance obligation at contract inception based on the estimated transaction price of each performance obligation. Revenue allocated to each performance obligation is then recognized when we satisfy the performance obligation by transferring control of the promised good or service to the customer. Collaboration and manufacturing service revenue are recorded in other revenue in the condensed consolidated statements of operations. Leases On January 1, 2019, we adopted ASC 842, Leases, using the modified retrospective approach. Prior period amounts continue to be reported in accordance with our historic accounting under previous lease guidance, ASC 840, Leases. We elected the package of practical expedients which, among other things, allowed us to carry forward the historical lease classification of leases in place as of January 1, 2019. We have also elected the practical expedient to not separate lease components from non-lease components. As a result of adopting ASC 842, we recognized right-of-use asset and lease liabilities for operating leases of $34.8 million and $37.1 million, respectively on January 1, 2019. There was no adjustment to the opening balance of accumulated deficit as a result of the adoption of ASC 842. We determine if an arrangement includes a lease at inception. Operating leases are included in operating lease right-of-use assets, other current liabilities and long-term portion of lease liabilities in our condensed consolidated balance sheets. Right-of-use assets represent our right to use an underlying asset during the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, we use our incremental borrowing rate which represents an estimated rate of interest that we would have to pay to borrow equivalent funds on a collateralized basis at the lease commencement date. The operating lease right-of-use assets also include any lease payments made and exclude any lease incentives. Our leases may include options to extend or terminate the lease which are included in the lease term when it is reasonably certain that we will exercise any such options. Lease expense is recognized on a straight-line basis over the expected lease term. We have elected not to apply the recognition requirements of ASC 842 for short-term leases. As lessors, we determine if an arrangement includes a lease at inception. We elected the practical expedient to not separate lease components from non-lease components. Rent revenue is recognized on a straight-line basis over the expected lease term and is included in other income (expense) in our condensed consolidated statements of operations. Inventories Inventory is stated at the lower of cost or estimated net realizable value, on a first-in, first-out, or FIFO, basis. We primarily use actual costs to determine our cost basis for inventories. Our assessment of market value requires the use of estimates regarding the net realizable value of our inventory balances, including an assessment of excess or obsolete inventory. We determine excess or obsolete inventory based on multiple factors, including an estimate of the future demand for our products, product expiration dates and current sales levels. Our assumptions of future demand for our products are inherently uncertain and if we were to change any of these judgments or estimates, it could cause a material increase or decrease in the amount of inventory reserves that we report in a particular period. For the nine months ended September 30, 2019, there was no inventory reserve recognized. We consider regulatory approval of product candidates to be uncertain and product manufactured prior to regulatory approval may not be sold unless regulatory approval is obtained. As such, the manufacturing costs for product candidates incurred prior to regulatory approval are not capitalized as inventory but are expensed as research and development costs. We begin capitalization of these inventory related costs once regulatory approval is obtained. HEPLISAV-B was approved by the FDA on November 9, 2017, at which time we began to capitalize inventory costs associated with the vial presentation of HEPLISAV-B. In March 2018, we received regulatory approval of the pre-filled syringe (“PFS”) presentation of HEPLISAV-B. Prior to FDA approval of HEPLISAV-B, all costs related to the manufacturing of HEPLISAV-B that could potentially be available to support the commercial launch of our products, were charged to research and development expense in the period incurred as there was no alternative future use. Prior to regulatory approval of PFS, costs associated with resuming operating activities at the Düsseldorf manufacturing facility were also included in research and development expense. Subsequent to regulatory approval of PFS, costs associated with resuming manufacturing activities at the Düsseldorf facility were included in cost of sales – product, until commercial production resumed in mid-2018 at which time these costs were recorded as raw materials inventory. Research and Development Expenses and Accruals Research and development expenses include personnel and facility-related expenses, outside contracted services including clinical trial costs, manufacturing and process development costs, research costs and other consulting services and non-cash stock-based compensation. Research and development costs are expensed as incurred. Amounts due under contracts with third parties may be either fixed fee or fee for service, and may include upfront payments, monthly payments and payments upon the completion of milestones or receipt of deliverables. Non-refundable advance payments under agreements are capitalized and expensed as the related goods are delivered or services are performed. We contract with third parties to perform various clinical trial activities in the on-going development of potential products. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows to our vendors. Payments under the contracts depend on factors such as the achievement of certain events, successful enrollment of patients, and completion of portions of the clinical trial or similar conditions. Our accrual for clinical trials is based on estimates of the services received and efforts expended pursuant to contracts with clinical trial centers and clinical research organizations. We may terminate these contracts upon written notice and we are generally only liable for actual effort expended by the organizations to the date of termination, although in certain instances we may be further responsible for termination fees and penalties. We estimate research and development expenses and the related accrual as of each balance sheet date based on the facts and circumstances known to us at that time. There have been no material adjustments to the prior period accrued estimates for clinical trial activities for the nine months ended September 30, 2019 . Restructuring Restructuring costs are comprised of severance, other termination benefit costs, stock-based compensation expense for stock award and stock option modifications related to workforce reductions and accelerated depreciation. We recognize restructuring charges when the liability is probable and the amount is estimable. Employee termination benefits are accrued at the date management has committed to a plan of termination and affected employees have been notified of their termination date and expected severance benefits. Recent Accounting Pronouncements Accounting Standards Update 2016-13 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments. The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. In April 2019, the FASB issued targeted clarification to ASU No. 2016-13 within ASU No. 2019-04. In May 2019, the FASB issued targeted transition relief to ASU No. 2016-13 within ASU No. 2019-05. These ASUs are effective for annual periods beginning after December 15, 2019 with early adoption permitted. We are currently evaluating the impact this standard will have on our condensed consolidated financial statements. Accounting Standards Update 2017-04 In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350), which simplifies the test for goodwill impairment by eliminating a previous requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. The ASU is effective for annual periods beginning after December 15, 2019 with early adoption permitted. The adoption is not expected to have a material impact on our condensed consolidated financial statements. Accounting Standards Update 2018-13 In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), that eliminates, adds and modifies certain disclosure requirements of fair value measurements. Entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The ASU is effective for annual periods beginning after December 15, 2019 with early adoption permitted. The adoption of this standard is not expected to have a material impact on our condensed consolidated financial statements. Accounting Standards Update 2018-15 In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other –Internal-Use Software (Subtopic 350-40). This ASU requires a customer in a cloud computing arrangement (i.e. hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. ASC 350-40 requires that certain costs incurred during the application development stage be capitalized and other costs incurred during the preliminary project and post-implementation stages be expensed as incurred. The ASU is effective for annual periods beginning after December 15, 2019 with early adoption permitted. The adoption of this standard is not expected to have a material impact on our condensed consolidated financial statements. |

Fair Value Disclosures [Abstract] | |
Fair Value Measurements | 2. Fair Value Measurements We measure fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The accounting standard describes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that may be used to measure fair value which are the following: • Level 1—Observable inputs, such as quoted prices in active markets for identical assets or liabilities; • Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities; and • Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities; therefore, requiring an entity to develop its own valuation techniques and assumptions. Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. We review the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The carrying amounts of cash equivalents, accounts and other receivables, accounts payable and accrued liabilities are considered reasonable estimates of their respective fair value because of their short-term nature. Recurring Fair Value Measurements The following table represents the fair value hierarchy for our financial assets (cash equivalents and marketable securities) and liabilities measured at fair value on a recurring basis (in thousands): Level 1 Level 2 Level 3 Total September 30, 2019 Assets Money market funds $ 33,732 $ - $ - $ 33,732 U.S. treasuries - 1,497 - 1,497 U.S. government agency securities - 58,719 - 58,719 Corporate debt securities - 77,433 - 77,433 Total assets $ 33,732 $ 137,649 $ - $ 171,381 Liabilities Warrant liability $ - $ - $ 7,594 $ 7,594 Sublicense liability - - 6,791 6,791 Total liabilities $ - $ - $ 14,385 $ 14,385 Level 1 Level 2 Level 3 Total December 31, 2018 Assets Money market funds $ 44,002 $ - $ - $ 44,002 U.S. treasuries - 14,724 - 14,724 U.S. government agency securities - 42,372 - 42,372 Corporate debt securities - 41,291 - 41,291 Total assets $ 44,002 $ 98,387 $ - $ 142,389 Liabilities Sublicense liability $ - $ - $ 6,320 $ 6,320 Money market funds are highly liquid investments and are actively traded. The pricing information on these investment instruments is readily available and can be independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy. U.S. treasuries, U.S. government agency securities and corporate debt securities are measured at fair value using Level 2 inputs. We review trading activity and pricing for these investments as of each measurement date. When sufficient quoted pricing for identical securities is not available, we use market pricing and other observable market inputs for similar securities obtained from various third-party data providers. These inputs represent quoted prices for similar assets in active markets or these inputs have been derived from observable market data. This approach results in the classification of these securities as Level 2 of the fair value hierarchy. There were no transfers between Level 1 and Level 2 during the nine months ended September 30, 2019. Warrants were issued in connection with the underwritten public offering in August 2019 and are accounted for as a derivative liability at fair value. See Note 11. The fair value of the warrant liability is estimated using the Black-Scholes model which requires assumptions such as expected term, expected volatility and risk-free interest rate. These assumptions are subjective and require judgement to develop. Expected term is estimated using the full remaining contractual term of the warrants. We determine expected volatility based on our historical common stock price volatility. The warrant liability is classified as a Level 3 instrument as its value is based on unobservable inputs that are supported by little or no market activity. As of September 30, 2019, we used the following key assumptions to estimate the fair value of warrant liability: Number of shares 5,841,250 Expected term 2.4 years Expected volatility 0.7 Risk-free interest rate 1.6 % Dividend yield 0 % The following table provides a summary of changes in the fair value warrant liability for nine month ended September 30, 2019 (in thousands): Balance at December 31, 2018 $ - Fair value of warrant liability at issuance date 7,360 Increase in estimated fair value of warrant liability upon revaluation 234 Balance at September 30, 2019 $ 7,594 As of September 30, 2019, we measured the fair value of our $7.0 million payment to Merck Sharpe & Dohme Corp., which is due in the first quarter of 2020, based on Level 3 inputs due to the use of unobservable inputs that cannot be corroborated by observable market data. We estimated the fair value of the liability using a discounted cash flow technique using the effective interest rate on our term loan. The liability had a fair value of $6.8 million as of September 30, 2019. |

We have classified our entire investment portfolio as available-for-sale and available for use in current operations and accordingly have classified all investments as short-term. Available-for-sale securities are carried at fair value based on inputs that are observable, either directly or indirectly, such as quoted market prices for similar securities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the securities, with unrealized gains and losses included in accumulated other comprehensive loss in stockholders’ equity. Realized gains and losses and declines in value, if any, judged to be other than temporary on available-for-sale securities are included in interest income or expense. The cost of securities sold is based on the specific identification method. Management assesses whether declines in the fair value of investment securities are other than temporary. In determining whether a decline is other than temporary, management considers the following factors: • whether the investment has been in a continuous realized loss position for over 12 months; • the duration to maturity of our investments; • our intention and ability to hold the investment to maturity and if it is not more likely than not that we will be required to sell the investment before recovery of the amortized cost bases; • the credit rating, financial condition and near-term prospects of the issuer; and • the type of investments made. To date, there have been no declines in fair value that have been identified as other than temporary. |

Commitments And Contingencies Disclosure [Abstract] | |
Commitments and Contingencies | 6. Commitments and Contingencies Leases As described in Note 1, we adopted ASC 842 as of January 1, 2019. We evaluated our contracts and have determined that, effective upon the adoption of ASC 842, our operating leases included equipment, office/laboratory and manufacturing facility leases. We lease our facilities in Emeryville, California and Düsseldorf, Germany. In July 2019, we entered into a sublease for office space located at 2100 Powell Street, Emeryville, California (the “Powell Street Sublease”) and the lease for our former corporate headquarters at 2929 Seventh Street, Berkeley, California was terminated effective August 31, 2019. Under the terms of the Powell Street Sublease, we are leasing 23,976 square feet at the rate of $3.90 per square foot, paid on a monthly basis. Rent is subject to scheduled annual increases and we are responsible for certain operating expenses and taxes throughout the life of the Powell Street Sublease. The Powell Street Sublease will continue until June 30, 2022. There is no option to extend the sublease term. On September 17, 2018, we entered into a lease (“Horton Street Master Lease”) for office and laboratory space located at 5959 Horton Street, Emeryville, California (“Horton Street Premises”). Under the terms of the Horton Street Master Lease, we are leasing 75,662 square feet at Horton Street Premises at the rate of $4.75 per square foot, paid on a monthly basis, starting on April 1, 2019 (“Commencement Date”). Rent is subject to scheduled annual increases, and we are also responsible for certain operating expenses and taxes throughout the life of Horton Street Master Lease. In connection with the Horton Street Master Lease, we are entitled to a tenant improvement allowance of up to $8.3 million. The Horton Street Master Lease has an initial term of 12 years, following the Commencement Date with an option to extend the lease for two successive five-year terms. The optional periods were not included in the lease term used in determining the right-of-use asset or the lease liability as we did not consider it reasonably certain that we would exercise the options. The operating lease right-of-use assets and liabilities on our September 30, 2019 condensed consolidated balance sheets primarily relate to the Horton Street Master Lease. In July 2019, we entered into an agreement to sublease the Horton Street Premises to another company (“Horton Street Sublease”). We had previously intended to use the Horton Street Premises as our new corporate headquarters. In connection with the organizational restructuring (see Note 13), we do not intend to occupy any of the Horton Street Premises. Under the terms of the Horton Street Sublease, we are subleasing the entire 75,662 rentable square feet at the rate of $5.50 per square foot, paid on a monthly basis. Rent is subject to scheduled annual increases and the subtenant (“Subtenant”) is responsible for certain operating expenses and taxes throughout the life of the Horton Street Sublease. The Horton Street Sublease will continue until March 31, 2031, unless earlier terminated, concurrent with the term of our Horton Street Master Lease. The Subtenant has no option to extend the sublease term. For the three and nine months ended September 30, 2019, we recognized $0.9 million of sublease income included in other income (expense) in our condensed consolidated statements of operations. Under the terms of the Horton Street Master Lease, rent received from the Subtenant in excess of rent paid to the landlord shall be shared by paying the landlord 50% of the excess rent. The excess rent is considered a variable lease payment and the total estimated payments are being recognized as additional rent expense on a straight-line basis. Our lease expense comprises of the following (in thousands): Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Operating lease expense $ 1,789 $ 821 $ 5,274 $ 2,212 Cash paid for amounts included in the measurement of lease liabilities for the nine months ended September 30, 2019 was $3.8 million and was included in operating cash flows in our condensed consolidated statement of cash flows. The balance sheet classification of our operating lease liabilities was as follows (in thousands): September 30, 2019 December 31, 2018 Operating lease liabilities: Current portion of lease liabilities (included in other current liabilities) $ 3,058 $ - Long-term portion of lease liabilities 36,964 - Total operating lease liabilities $ 40,022 $ - At September 30, 2019, the maturities of our sublease income and operating lease liabilities were as follows (in thousands): Years ending December 31, Sublease Income Operating Lease Liabilities 2019 (remaining) $ - $ 1,723 2020 4,446 7,007 2021 5,202 6,935 2022 5,358 6,185 2023 5,519 4,946 Thereafter 45,285 39,523 Total $ 65,810 66,319 Less: Present value adjustment (26,297 ) Total $ 40,022 As of September 30, 2019, the weighted average remaining lease term is 9.8 years and the weighted average discount rate used to determine the operating lease liability was 10.1%. Commitments In February 2018, we entered into a $175.0 million term loan agreement. Borrowings under the term loan agreement in the amount of $179.1 million , which includes paid-in-kind interest, In February 2018, we entered into a sublicense agreement with Merck Sharpe & Dohme Corp (“Merck”). Under the agreement, we are required to make a payment of $7.0 million in the first quarter of 2020. See Note 7. As of September 30, 2019, our material non-cancelable purchase and other commitments, for the supply of HEPLISAV-B and for clinical research, totaled $13.0 million. Contingencies From time to time, we may be involved in claims, suits, and proceedings arising from the ordinary course of our business, including actions with respect to intellectual property claims, commercial claims, and other matters. Such claims, suits, and proceedings are inherently uncertain and their results cannot be predicted with certainty. Regardless of the outcome, such legal proceedings can have an adverse impact on us because of legal costs, diversion of management resources, and other factors. In addition, it is possible that a resolution of one or more such proceedings could result in substantial damages, fines, penalties or orders requiring a change in our business practices, which could in the future materially and adversely affect our financial position, results of operations, or cash flows in a particular period. In conjunction with a financing arrangement with Symphony Dynamo, Inc. and Symphony Dynamo Holdings LLC (“Holdings”) in November 2009, we agreed to make contingent cash payments to Holdings equal to 50% of the first $50 million from any upfront, pre-commercialization milestone or similar payments received by us from any agreement with any third-party with respect to the development and/or commercialization of cancer and hepatitis C therapies originally licensed to Symphony Dynamo, Inc., including SD-101. We have made no payments and have not recorded a liability as of September 30, 2019. |

Collaborative Research, Development and License Agreements | 7. Collaborative Research, Development and License Agreements Serum Institute of India Pvt. Ltd. In June 2017, we entered into an agreement to provide Serum Institute of India Pvt. Ltd. (“SIIPL”) with technical support. In consideration, SIIPL agreed to pay us at an agreed-upon hourly rate for services and reimburse certain out-of-pocket expenses. In addition, we have rights to commercialization of certain potential products manufactured at the SIIPL facility. For the nine months ended September 30, 2019, we recognized collaboration revenue of $0.1 million. No collaborative revenue was recognized for the comparative prior period. Merck, Sharp & Dohme Corp. In February 2018, we entered into a Sublicense Agreement (the “Sublicense Agreement”) with Merck. The Sublicense Agreement grants us, under certain non-exclusive U.S. patent rights controlled by Merck which relate to recombinant production of hepatitis B surface antigen, the right to manufacture, use, offer for sale, sell and import HEPLISAV-B in the United States and includes the right to grant further sublicenses. Under the terms of the Sublicense Agreement, we are obligated to pay $21.0 million in three installments. The first and second installment of $7.0 million each was paid in February 2018 and February 2019, respectively and the remaining payment of $7.0 million is due in the first quarter of 2020. The payment in 2020 is classified on the condensed consolidated balance sheets as other current liabilities. At September 30, 2019 and December 31, 2018, the intangible asset, net balance was $4.8 million and $11.7 million, respectively. See Note 5. The Sublicense Agreement continues to be in effect through April 2020, at which time the license becomes perpetual, irrevocable, fully paid-up and royalty free. |

Debt Disclosure [Abstract] | |
Long-Term Debt | 8. Long-Term Debt On February 20, 2018, we entered into a $175.0 million term loan agreement (“Loan Agreement”) with CRG Servicing LLC. We borrowed $100.0 million (the “Initial Term Loan”) under the Loan Agreement at closing and the remaining $75.0 million (the “Second Tranche Term Loan”) in March 2019 (collectively, “Term Loans”). Net proceeds from the Initial Term Loan and Second Tranche Term Loan were $99.0 million and $74.3 million, respectively. The Term Loans under the Loan Agreement bear interest at a rate equal to 9.5% per annum. At September 30, 2019, the effective interest rate was 10.3%. At our option, until September 30, 2023, a portion of the interest payments may be paid in kind, and thereby added to the principal. Through September 30, 2019, a portion of our interest was paid in kind, which increased the principal amount of the Term Loans to $179.1 million. The Term Loans have a maturity date of December 31, 2023, unless earlier prepaid. The Term Loans and paid-in-kind interest will be entirely payable at maturity. In August 2019, we entered into a second amendment to the Loan Agreement (the “Second Amendment”). The Second Amendment amended the annual net sales threshold for sales of HEPLISAV-B, revising the twelve-month measurement periods from beginning on January 1 of each year to beginning on July 1 of each year (including 2019), and removing this requirement for the period subsequent to July 1, 2022. The Second Amendment also revised the fee payable upon partial prepayment or at maturity of the Term Loans from 3% to 4% of the aggregate principal amounts. The obligations under the Loan Agreement are secured, subject to customary permitted liens and other agreed upon exceptions, by a perfected security interest in (i) all tangible and intangible assets of the Company and any future subsidiary guarantors, except for certain customary excluded property, and (ii) all of the capital stock owned by the Company and such future subsidiary guarantors (limited, in the case of the stock of certain non-U.S. subsidiaries of the Company and certain U.S. subsidiaries substantially all of whose assets consist of equity interests in non-U.S. subsidiaries, to 65% of the capital stock of such subsidiaries, subject to certain exceptions). The obligations under the Loan Agreement will be guaranteed by each of the Company’s future direct and indirect subsidiaries (other than certain non-U.S. subsidiaries of the Company and certain U.S. subsidiaries substantially all of whose assets consist of equity interests in non-U.S. subsidiaries, subject to certain exceptions). The Loan Agreement contains customary covenants and requires us to comply with a $15.0 million daily minimum combined cash and investment balance covenant and a twelve-month period revenue requirement starting on July 1, 2019 for sales of HEPLISAV-B. The Term Loans may be prepaid by us at any time. If the Term Loans are prepaid prior to the second anniversary of the initial borrowing date, we are subject to a repayment premium of up to 7.0% of the principal amount prepaid, depending on the date of prepayment. We recorded $4.7 million and $2.6 million of interest expense related to the Term Loans during the three months ended September 30, 2019 and 2018, respectively. We recorded $11.8 million and $6.2 million of interest expense related to the Term Loans during the nine months ended September 30, 2019 and 2018, respectively. |

Revenue Recognition | 9. Revenue Recognition All of our product revenue consisted of sales of HEPLISAV-B in the U.S. For the nine months ended September 30, 2019 and 2018, our three largest Customers collectively represented approximately 63% and 68% of our product revenue, respectively. The following table summarizes balances and activity in each of the product revenue allowance and reserve categories for the nine months ended September 30, 2019 (in thousands): Chargebacks, distribution fees, discounts and other fees Returns Total Balance at December 31, 2018 $ 1,736 $ 569 $ 2,305 Provision related to current period sales 10,937 1,724 12,661 Credit or payments made during the period (8,689 ) (408 ) (9,097 ) Balance at September 30, 2019 $ 3,984 $ 1,885 $ 5,869 Reserves for chargebacks and discounts totaling $2.7 million were recorded as reductions of accounts receivable at September 30, 2019. The remaining reserves balances totaling $3.2 million were recorded as accrued liabilities at September 30, 2019. |

Earnings Per Share [Abstract] | |
Net Loss Per Share | 10. Net Loss Per Share Basic net loss per share allocable to common stockholders is calculated by dividing the net loss allocable to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net loss per share allocable to common stockholders is computed by dividing the net loss allocable to common stockholders by the weighted-average number of common shares outstanding during the period and giving effect to all potentially dilutive common shares using the treasury-stock method. For purposes of this calculation, outstanding options, stock awards, warrants and Series B Convertible Preferred Stock are considered to be potentially dilutive common shares and are only included in the calculation of diluted net loss per share allocable to common stockholders when their effect is dilutive. As of September 30, 2019, stock options and stock awards, Series B Convertible Preferred Stock (on an as converted to common stock basis) and warrants (as exercisable into common stock), totaling approximately 10,065,000, 4,840,000 and 5,841,250 shares of common stock, respectively were excluded from the calculation of diluted net loss per share for the three and nine months ended September 30, 2019, because the effect of their inclusion would have been anti-dilutive. As of September 30, 2018, stock options and stock awards, totaling approximately 12,892,000 shares of common stock were excluded from the calculation of diluted net loss per share for the three and nine months ended September 30, 2018, because the effect of their inclusion would have been anti-dilutive. For periods in which we have a net loss and no instruments are determined to be dilutive, such as the three and nine months ended September 30, 2019 and 2018, basic and diluted net loss per share are the same. |

Preferred Stock Common Stock And Warrants [Abstract] | |
Common Stock,Preferred Stock and Warrants | 11. Common Stock, Preferred Stock and Warrants Common Stock Outstanding As of September 30, 2019, there were 83,865,119 shares of our common stock outstanding. In August 2019, we sold (i) 18,525,000 shares of our common stock, par value $0.001 per share, (ii) 4,840 shares of our Series B Preferred Stock, par value $0.001 per share (“Series B Preferred Stock”) and (iii) warrants to purchase up to an aggregate of 5,841,250 shares of our common stock in an underwritten public offering (the “Offering”). Each share of common stock was sold together with a warrant to purchase 0.25 shares of common stock, at a combined price of $3.00 per share of common stock and the accompanying warrant. Each share of Series B Preferred Stock was sold together with a warrant to purchase 250 shares of common stock, at a combined price of $3,000 per share and the accompanying warrant. Proceeds from the Offering were approximately $65.6 million, net of issuance costs of $4.5 million. On November 3, 2017, we entered into an At Market Sales Agreement (“2017 ATM Agreement”) with Cowen and Company, LLC (“Cowen”) under which we may offer and sell from time to time at our sole discretion, shares of our common stock having an aggregate offering price up to $150 million through Cowen as our sales agent. We pay Cowen a commission of up to 3% of the gross sales proceeds of any common stock sold through Cowen under the 2017 ATM Agreement. For the nine months ended September 30, 2019, we received net cash proceeds of $13.9 million resulting from sales of 1,386,906 shares of our common stock. As of September 30, 2019, we have $118.6 million remaining under the 2017 ATM Agreement. Preferred Stock Outstanding As of September 30, 2019, there were 4,840 shares of Series B Preferred Stock outstanding. Each share of Series B Preferred Stock is convertible into 1,000 shares of common stock at any time at the holder’s option. However, the holder is prohibited from converting the Series B Preferred Stock into shares of common stock if, as a result of such conversion, the holder and its affiliates would own more than 4.99% of the total number of shares of common stock then issued and outstanding, which percentage may be changed at the holders’ election to a higher or lower percentage (not to exceed 19.99%) upon 61 days’ notice to the Company. In the event of liquidation, dissolution, or winding up, the holder of Series B Preferred Stock will receive payment on shares of Series B Preferred Stock (determined on an as-converted to common stock basis) equal to the amount that would be paid on our common stock. Shares of Series B Preferred Stock generally have no voting rights, except as required by law and except that the consent of holders of a majority of the outstanding Series B Preferred Stock is required to amend the terms of the Series B Preferred Stock. Holders of Series B Preferred Stock are not entitled to receive any dividends, unless and until specifically declared by our board of directors. The Series B Preferred Stock ranks on parity with our common stock as to distributions of assets upon liquidation, dissolution or winding up. The Series B Preferred Stock may rank senior to, on parity with or junior to any class or series of capital stock created in the future depending upon the specific terms of such future stock issuance. The fair value of the common stock into which the Series B Preferred Stock is convertible exceeded the allocated purchase price of the Series B Preferred Stock by $3.3 million on the date of issuance, for which we recorded a deemed dividend. We recognized a deemed dividend equal to the number of common stock into which the Series B Preferred Stock is convertible multiplied by the difference between the value of the common stock and the Series B Preferred Stock conversion price per share on the date of issuance, which is the date the stock first became convertible. The dividend was reflected as a one-time, non-cash, deemed dividend to the holders of Series B Preferred Stock on the date of issuance. Warrants As of September 30, 2019, the following common stock warrants were outstanding: Warrants Issuance Date Shares Issuable (in thousands) Expiration Date Exercise Price per Share Outstanding as of September 30, 2019 (in thousands) August 12, 2019 5,841 February 12, 2022 $ 4.50 5,841 Warrants were exercisable upon issuance. The holder is prohibited from exercising these warrants if, as a result of such exercise, the holder and its affiliates, would own more than 4.99% of the total number of shares of common stock then issued and outstanding, which percentage may be changed at the holders’ election to a higher or lower percentage (not to exceed 19.99%) upon 61 days’ notice to the Company. The warrants contain provisions that may obligate us to repurchase them for an amount that does not represent fair value in the event of a change of control. Due to this provision, the warrants do not meet the criteria to be considered indexed to our own stock. Accordingly, we recorded the warrants as a derivative liability at fair value of $7.4 million on the issuance date, which was estimated using the Black-Scholes model. The warrants will be revalued at each reporting period using the Black-Scholes model and the change in the fair value of the warrants will recognized as other income (expense) in the condensed consolidated statements of operations. At September 30, 2019, the estimated fair value of warrant liability was $7.6 million. For the three and nine months ended September 30, 2019, we recognized the $0.2 million increase in the estimated fair value as a loss on warrant liability in other income, net in our condensed consolidated statements of operations. |

Share Based Compensation [Abstract] | |
Equity Plans and Stock-Based Compensation | 12. Equity Plans and Stock-Based Compensation Our 2018 Equity Incentive Plan (the “2018 EIP”) is intended to be the successor to and continuation of the Dynavax Technologies Corporation 2011 Equity Incentive Plan (the “2011 EIP”). The aggregate number of shares of our common stock that may be issued under the 2018 EIP (subject to adjustment for certain changes in capitalization) is comprised of the sum of (i) 5,000,000 newly reserved shares of common stock, (ii) 140,250 unallocated shares of common stock remaining available for grant under the 2011 EIP as of May 31, 2018, and (iii) 7,477,619 shares subject to outstanding stock awards granted under the 2011 EIP and the Dynavax Technologies Corporation 2017 Inducement Award Plan that may become available from time to time as set forth in the 2018 EIP. The 2018 EIP provides for the issuance of up to 12,617,869 shares of our common stock to our employees and directors. On May 30, 2019, our stockholders approved an amendment to 2018 Equity Incentive Plan (the “Amended 2018 EIP”) to, among other things, increase the aggregate number of shares of common stock authori zed for issuance by 2,300,000 . Under the Amended 2018 EIP, the aggregate number of shares of our common stock that may be issued to employees and directors (subject to adjustment for certain changes in capitalization) is 14,917,869 . Option activity under our stock-based compensation plans during the nine months ended September 30, 2019 was as follows (in thousands except per share amounts): Shares Underlying Outstanding Options Weighted-Average Exercise Price Per Share Weighted-Average Remaining Contractual Term (years) Aggregate Intrinsic Value Balance at December 31, 2018 5,750 $ 18.20 Options granted 3,025 6.94 Options exercised (10 ) 5.75 Options cancelled: Options forfeited (unvested) (632 ) 12.53 Options expired (vested) (136 ) 16.77 Balance at September 30, 2019 7,997 $ 14.43 4.57 $ 6 Vested and expected to vest at September 30, 2019 7,692 $ 14.70 4.51 $ 5 Exercisable at September 30, 2019 4,485 $ 18.40 3.57 $ - Restricted stock unit activity under our stock-based compensation plans during the nine months ended September 30, 2019 was as follows (in thousands except per share amounts): Number of Shares Weighted-Average Grant-Date Fair Value Per Share Non-vested as of December 31, 2018 1,594 $ 8.82 Granted 1,823 8.80 Vested (964 ) 6.72 Forfeited (385 ) 11.24 Non-vested as of September 30, 2019 2,068 $ 9.33 The aggregate intrinsic value of the restricted stock units outstanding as of September 30, 2019, based on our stock price on that date was $7.4 million. Fair value of restricted stock units is determined at the date of grant using our closing stock price. As of September 30, 2019, approximately 155,000 shares underlying stock options and approximately 111,000 restricted stock unit awards with performance-based vesting criteria were outstanding. Under our stock-based compensation plans, option awards generally vest over a three or four-year period contingent upon continuous service, and expire seven to ten years from the date of grant (or earlier upon termination of continuous service). The fair value-based measurement of each option is estimated on the date of grant using the Black-Scholes option valuation model. The fair value-based measurements and weighted-average assumptions used in the calculations of these measurements are as follows: Stock Options Stock Options Employee Stock Purchase Plan Three Months Ended Nine Months Ended Nine Months Ended September 30, September 30, September 30, 2019 2018 2019 2018 2019 2018 Weighted-average fair value per share $ 2.74 $ 9.36 $ 4.61 $ 10.91 $ 2.72 $ 8.30 Risk-free interest rate 1.6 % 2.8 % 2.2 % 2.6 % 1.9 % 2.4 % Expected life (in years) 4.5 4.5 4.5 4.5 1.3 1.3 Volatility 0.9 0.9 0.9 0.9 0.7 1.1 The components of stock-based compensation expense were (in thousands): Three Months Ended Nine Months Ended September 30, September 30, 2019 2018 2019 2018 Research and development $ 1,661 $ 2,332 $ 5,817 $ 7,194 Selling, general and administrative 2,278 2,976 7,828 8,561 Restructuring - - 4,122 - Cost of sales - product 189 443 819 1,085 Inventory 620 295 1,681 295 Total $ 4,748 $ 6,046 $ 20,267 $ 17,135 Compensation expense is based on awards ultimately expected to vest and reflects estimated forfeitures. Stock-based compensation cost for the nine months ended September 30, 2019 include incremental cost of $4.1 million for accelerated vesting of stock awards and extension of exercise period of stock options for the retirement of our Chief Executive Officer. See Note 13. As of September 30, 2019, the total unrecognized compensation cost related to non-vested equity awards including all awards with time-based vesting amounted to $30.5 million, which is expected to be recognized over the remaining weighted-average vesting period of 1.6 years. Additionally, as of September 30, 2019, the total unrecognized compensation cost related to equity awards with performance-based vesting criteria amounted to $0.4 million. Employee Stock Purchase Plan The Amended and Restated 2014 Employee Stock Purchase Plan (the “Purchase Plan”) provides for the purchase of common stock by eligible employees and became effective on May 28, 2014. On May 31, 2018, our stockholders approved an amendment to the Purchase Plan to increase the aggregate number of shares of common stock authorized for issuance by 600,000 shares. The purchase price per share is the lesser of (i) 85% of the fair market value of the common stock on the commencement of the offer period (generally, the sixteenth day in February or August) or (ii) 85% of the fair market value of the common stock on the exercise date, which is the last day of a purchase period (generally, the fifteenth day in February or August). For the nine months ended September 30, 2019, employees have acquired 122,117 shares of our common stock under the Purchase Plan and 450,917 shares of our common stock remained available for future purchases under the Purchase Plan. |

Restructuring And Related Activities [Abstract] | |
Restructuring | 13. Restructuring On May 23, 2019, we implemented a strategic organizational restructuring, principally to align our operations around our vaccine business and significantly curtail further investment in our immuno-oncology business. In connection with the restructuring, we reduced our workforce by approximately 80 positions, or approximately 36%, of U.S.-based personnel. Also, in connection with the restructuring, our Chief Executive Officer, also a member of the Board of Directors (the “Board”), submitted notice of his retirement from the Company and the Board, effective August 1, 2019. We expect the restructuring to be substantially complete and the costs incurred and paid by December 31, 2019. We are exploring strategic alternatives for our immuno-oncology business. During the three months ended September 30, 2019, we identified certain long-lived assets installed at the Horton Street Premises that were or will be disposed of by the Subtenant. We recorded accelerated depreciation charges of $3.0 million on these assets. The major components of our restructuring costs are summarized as follows (in thousands) . The remaining $0.8 million is expected to be recognized by the end of 2019.

Organization Consolidation And Presentation Of Financial Statements [Abstract] | |
Basis of Presentation | Basis of Presentation Our accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Article 10 of Regulation S-X. In our opinion, these unaudited condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which we consider necessary to present fairly our financial position and the results of our operations and cash flows. As permitted under those rules, certain footnotes or other financial information that are normally required by GAAP have been condensed or omitted. Interim-period results are not necessarily indicative of results of operations or cash flows to be expected for a full-year period or any other interim-period. The condensed consolidated balance sheet at December 31, 2018 has been derived from audited financial statements at that date, but excludes disclosures required by GAAP for complete financial statements. The unaudited condensed consolidated financial statements and these notes should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018, as filed with the Securities and Exchange Commission (the “SEC”). The unaudited condensed consolidated financial statements include the accounts of Dynavax and our wholly-owned subsidiary, Dynavax GmbH. All significant intercompany accounts and transactions among these entities have been eliminated from the condensed consolidated financial statements. We operate in one business segment: discovery, development and commercialization of novel vaccines. |
Liquidity and Financial Condition | Liquidity and Financial Condition As of September 30, 2019, we had cash, cash equivalents and marketable securities of $174.9 million. The Company has incurred losses and negative cash flows from operations since its inception and expects to incur operating losses for the foreseeable future as we continue to invest in commercialization of HEPLISAV-B. If we cannot generate a sufficient amount of revenue from product sales, we will need to finance our operations through strategic alliance and licensing arrangements and/or future public or private debt and equity financings. Adequate financing may not be available to us on acceptable terms, or at all. As of June 30, 2019, there was substantial doubt about the Company’s ability to continue as a going concern since it did not have sufficient financial resources available to fund its operations beyond the first quarter of 2020. In August 2019, the Company completed an underwritten public offering of common stock, non-voting preferred stock and warrants to purchase common stock resulting in net proceeds of $65.6 million. We currently anticipate that our cash, cash equivalents and short-term marketable securities as of September 30, 2019, and anticipated revenues from HEPLISAV-B will be sufficient to fund our operations for at least the next 12 months from the date of this filing. Our ability to raise additional capital in the equity and debt markets, should we choose to do so, is dependent on a number of factors, including, but not limited to, the market demand for our common stock, which itself is subject to a number of development and business risks and uncertainties, our creditworthiness and the uncertainty that we would be able to raise such additional capital at a price or on terms that are favorable to us. Raising additional funds through the issuance of equity or debt securities could result in dilution to our existing stockholders, increased fixed payment obligations, or both. In addition, these securities may have rights senior to those of our common stock and could include covenants that would restrict our operations . |
Use of Estimates | Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make informed estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Management’s estimates are based on historical information available as of the date of the condensed consolidated financial statements and various other assumptions we believe are reasonable under the circumstances. Actual results could differ materially from these estimates. |
Revenue Recognition | Revenue Recognition We recognize revenue when the customer obtains control of promised goods or services, in an amount that reflects the consideration which we expect to receive in exchange for those goods or services. To determine revenue recognition for arrangements that we determine are within the scope of Accounting Standards Codification (“ASC”) 606, we perform the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) we satisfy a performance obligation. We only apply the five-step model to contracts when it is probable that we will collect the consideration we are entitled to in exchange for the goods or services we transfer to the customer. At contract inception, once the contract is determined to be within the scope of ASC 606, we assess the goods or services promised within each contract and determine those that are performance obligations, and assess whether each promised good or service is distinct. We then recognize as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. Product Revenue, Net We sell our product to a limited number of wholesalers and specialty distributors in the U.S. (collectively, our “Customers”). Revenues from product sales are recognized when we have satisfied our performance obligation, which is the transfer of control of our product upon delivery to the Customer. The timing between the recognition of revenue for product sales and the receipt of payment is not significant. Because our standard credit terms are short-term and we expect to receive payment in less than one-year, there is no financing component on the related receivables. Taxes collected from Customers relating to product sales and remitted to governmental authorities are excluded from revenues. Overall, product revenue, net, reflects our best estimates of the amount of consideration to which we are entitled based on the terms of the contract. The amount of variable consideration is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. If our estimates differ significantly from actuals, we will record adjustments that would affect product revenue, net in the period of adjustment. Reserves for Variable Consideration Revenues from product sales are recorded at the net sales price, which includes estimates of variable consideration such as product returns, chargebacks, discounts, rebates and other fees that are offered within contracts between us and our Customers, healthcare providers, pharmacies and others relating to our product sales. We estimate variable consideration using either the most likely amount method or the expected value method, depending on the type of variable consideration and what method better predicts the amount of consideration we expect to receive. We take into consideration relevant factors such as industry data, current contractual terms, available information about Customers’ inventory, resale and chargeback data and forecasted customer buying and payment patterns, in estimating each variable consideration. The variable consideration is recorded at the time product sales is recognized, resulting in a reduction in product revenue and a reduction in accounts receivable (if the Customer offsets the amount against its accounts receivable) or as an accrued liability (if we pay the amount through our accounts payable process). Variable consideration requires significant estimates, judgment and information obtained from external sources. The amount of variable consideration is included in the net sales price only to the extent that it is probable that a significant reversal in the amount of the cumulative revenue recognized will not occur in a future period. If our estimates differ significantly from actuals, we will record adjustments that would affect product revenue, net in the period of adjustment. If we were to change any of these judgments or estimates, it could cause a material increase or decrease in the amount of revenue that we report in a particular period. There have been no material adjustments to these estimates for the nine months ended September 30, 2019. Product Returns: Consistent with industry practice, we offer our Customers a limited right of return based on the product’s expiration date for product th at has been purchased from us. We estimate the amount of our product sales that may be returned by our Customers and record this estimate as a reduction of revenue in the period the related product reven ue is recognized. We consider several factors in the estimation of potential product returns including expiration dates of the product shipped, the limited product return rights, available information about Customers’ inventory , shelf life of the product and other relevant factors. Chargebacks: Our Customers subsequently resell our product to healthcare providers, pharmacies and others. In addition to distribution agreements with Customers, we enter into arrangements with qualified healthcare providers that provide for chargebacks and discounts with respect to the purchase of our product. Chargebacks represent the estimated obligations resulting from contractual commitments to sell product to qualified healthcare providers at prices lower than the list prices charged to Customers who directly purchase the product from us. Customers charge us for the difference between what they pay for the product and the ultimate selling price to the qualified healthcare providers. These reserves are established in the same period that the related revenue is recognized, resulting in a reduction of product revenue and accounts receivable. Chargeback amounts are determined at the time of resale to the qualified healthcare providers by Customers, and we issue credits for such amounts generally within a few weeks of the Customer’s notification to us of the resale. Reserves for chargebacks consists of credits that we expect to issue for units that remain in the distribution channel inventories at each reporting period end that we expect will be sold to the qualified healthcare providers, and chargebacks for units that our Customers have sold to the qualified healthcare providers, but for which credits have not been issued. Trade Discounts and Allowances: We provide our Customers with discounts which include early payment incentives that are explicitly stated in our contracts, and are recorded as a reduction of revenue in the period the related product revenue is recognized. Distribution Fees: Distribution fees include fees paid to certain Customers for sales order management, data and distribution services. Distribution fees are recorded as a reduction of revenue in the period the related product revenue is recognized. Rebates: Under certain contracts, customers may obtain rebates for purchasing minimum volumes of our product. We estimate these rebates based upon the expected purchases and the contractual rebate rate and record this estimate as a reduction in revenue in the period the related revenue is recognized. Collaboration and Manufacturing Service Revenue We have entered into collaborative arrangements and arrangements to provide manufacturing services to other companies. Such arrangements may include promises to customers which, if capable of being distinct, are accounted for as separate performance obligations. For agreements with multiple performance obligations, we allocate estimated revenue to each performance obligation at contract inception based on the estimated transaction price of each performance obligation. Revenue allocated to each performance obligation is then recognized when we satisfy the performance obligation by transferring control of the promised good or service to the customer. Collaboration and manufacturing service revenue are recorded in other revenue in the condensed consolidated statements of operations. |
Leases | Leases On January 1, 2019, we adopted ASC 842, Leases, using the modified retrospective approach. Prior period amounts continue to be reported in accordance with our historic accounting under previous lease guidance, ASC 840, Leases. We elected the package of practical expedients which, among other things, allowed us to carry forward the historical lease classification of leases in place as of January 1, 2019. We have also elected the practical expedient to not separate lease components from non-lease components. As a result of adopting ASC 842, we recognized right-of-use asset and lease liabilities for operating leases of $34.8 million and $37.1 million, respectively on January 1, 2019. There was no adjustment to the opening balance of accumulated deficit as a result of the adoption of ASC 842. We determine if an arrangement includes a lease at inception. Operating leases are included in operating lease right-of-use assets, other current liabilities and long-term portion of lease liabilities in our condensed consolidated balance sheets. Right-of-use assets represent our right to use an underlying asset during the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. In determining the net present value of lease payments, we use our incremental borrowing rate which represents an estimated rate of interest that we would have to pay to borrow equivalent funds on a collateralized basis at the lease commencement date. The operating lease right-of-use assets also include any lease payments made and exclude any lease incentives. Our leases may include options to extend or terminate the lease which are included in the lease term when it is reasonably certain that we will exercise any such options. Lease expense is recognized on a straight-line basis over the expected lease term. We have elected not to apply the recognition requirements of ASC 842 for short-term leases. As lessors, we determine if an arrangement includes a lease at inception. We elected the practical expedient to not separate lease components from non-lease components. Rent revenue is recognized on a straight-line basis over the expected lease term and is included in other income (expense) in our condensed consolidated statements of operations. |
Inventories | Inventories Inventory is stated at the lower of cost or estimated net realizable value, on a first-in, first-out, or FIFO, basis. We primarily use actual costs to determine our cost basis for inventories. Our assessment of market value requires the use of estimates regarding the net realizable value of our inventory balances, including an assessment of excess or obsolete inventory. We determine excess or obsolete inventory based on multiple factors, including an estimate of the future demand for our products, product expiration dates and current sales levels. Our assumptions of future demand for our products are inherently uncertain and if we were to change any of these judgments or estimates, it could cause a material increase or decrease in the amount of inventory reserves that we report in a particular period. For the nine months ended September 30, 2019, there was no inventory reserve recognized. We consider regulatory approval of product candidates to be uncertain and product manufactured prior to regulatory approval may not be sold unless regulatory approval is obtained. As such, the manufacturing costs for product candidates incurred prior to regulatory approval are not capitalized as inventory but are expensed as research and development costs. We begin capitalization of these inventory related costs once regulatory approval is obtained. HEPLISAV-B was approved by the FDA on November 9, 2017, at which time we began to capitalize inventory costs associated with the vial presentation of HEPLISAV-B. In March 2018, we received regulatory approval of the pre-filled syringe (“PFS”) presentation of HEPLISAV-B. Prior to FDA approval of HEPLISAV-B, all costs related to the manufacturing of HEPLISAV-B that could potentially be available to support the commercial launch of our products, were charged to research and development expense in the period incurred as there was no alternative future use. Prior to regulatory approval of PFS, costs associated with resuming operating activities at the Düsseldorf manufacturing facility were also included in research and development expense. Subsequent to regulatory approval of PFS, costs associated with resuming manufacturing activities at the Düsseldorf facility were included in cost of sales – product, until commercial production resumed in mid-2018 at which time these costs were recorded as raw materials inventory. |
Research and Development Expenses and Accruals | Research and Development Expenses and Accruals Research and development expenses include personnel and facility-related expenses, outside contracted services including clinical trial costs, manufacturing and process development costs, research costs and other consulting services and non-cash stock-based compensation. Research and development costs are expensed as incurred. Amounts due under contracts with third parties may be either fixed fee or fee for service, and may include upfront payments, monthly payments and payments upon the completion of milestones or receipt of deliverables. Non-refundable advance payments under agreements are capitalized and expensed as the related goods are delivered or services are performed. We contract with third parties to perform various clinical trial activities in the on-going development of potential products. The financial terms of these agreements are subject to negotiation, vary from contract to contract and may result in uneven payment flows to our vendors. Payments under the contracts depend on factors such as the achievement of certain events, successful enrollment of patients, and completion of portions of the clinical trial or similar conditions. Our accrual for clinical trials is based on estimates of the services received and efforts expended pursuant to contracts with clinical trial centers and clinical research organizations. We may terminate these contracts upon written notice and we are generally only liable for actual effort expended by the organizations to the date of termination, although in certain instances we may be further responsible for termination fees and penalties. We estimate research and development expenses and the related accrual as of each balance sheet date based on the facts and circumstances known to us at that time. There have been no material adjustments to the prior period accrued estimates for clinical trial activities for the nine months ended September 30, 2019 . |
Restructuring | Restructuring Restructuring costs are comprised of severance, other termination benefit costs, stock-based compensation expense for stock award and stock option modifications related to workforce reductions and accelerated depreciation. We recognize restructuring charges when the liability is probable and the amount is estimable. Employee termination benefits are accrued at the date management has committed to a plan of termination and affected employees have been notified of their termination date and expected severance benefits. |
Recent Accounting Pronouncements | Recent Accounting Pronouncements Accounting Standards Update 2016-13 In June 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments. The standard changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. In April 2019, the FASB issued targeted clarification to ASU No. 2016-13 within ASU No. 2019-04. In May 2019, the FASB issued targeted transition relief to ASU No. 2016-13 within ASU No. 2019-05. These ASUs are effective for annual periods beginning after December 15, 2019 with early adoption permitted. We are currently evaluating the impact this standard will have on our condensed consolidated financial statements. Accounting Standards Update 2017-04 In January 2017, the FASB issued ASU No. 2017-04, Intangibles – Goodwill and Other (Topic 350), which simplifies the test for goodwill impairment by eliminating a previous requirement to calculate the implied fair value of goodwill to measure a goodwill impairment charge. The ASU is effective for annual periods beginning after December 15, 2019 with early adoption permitted. The adoption is not expected to have a material impact on our condensed consolidated financial statements. Accounting Standards Update 2018-13 In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), that eliminates, adds and modifies certain disclosure requirements of fair value measurements. Entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, but public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The ASU is effective for annual periods beginning after December 15, 2019 with early adoption permitted. The adoption of this standard is not expected to have a material impact on our condensed consolidated financial statements. Accounting Standards Update 2018-15 In August 2018, the FASB issued ASU No. 2018-15, Intangibles – Goodwill and Other –Internal-Use Software (Subtopic 350-40). This ASU requires a customer in a cloud computing arrangement (i.e. hosting arrangement) that is a service contract to follow the internal-use software guidance in ASC 350-40 to determine which implementation costs to capitalize as assets or expense as incurred. ASC 350-40 requires that certain costs incurred during the application development stage be capitalized and other costs incurred during the preliminary project and post-implementation stages be expensed as incurred. The ASU is effective for annual periods beginning after December 15, 2019 with early adoption permitted. The adoption of this standard is not expected to have a material impact on our condensed consolidated financial statements. |
